Abstract:
A reconnaisance survey of both coastal features in Granite Harbour and nunataks on the south side of the Mackay Glacier was conducted to search for evidence of Holocene glacier expansion both at sea level and well above the present day Mackay Glacier Tongue grounding line. Several coastal sites including Cape Roberts, Botany Bay, Cape GeoLogy, New Glacier terminus, Devils Punchbowl, Finger Point, ... Cuff Cape, the north side of the Mackay Glacier Tongue and Point Retreat were visited for indicators of previous ice levels in the harbour. The features found were unlikely to give datable evidence. A detailed survey of the moraine ridges at Cuff Cape was carried out with the ridge system surveyed and aerial photographs taken. The ridge system is associated with a small hanging glacier to the south the Cape rather than the Mackay Glacier Tongue was surveyed.
